Barely works, sometimes it picks the color correctly, other times it picks some random color thats 50px off to the side

The extension just helps to diversify the browser, thank you.

Gabriel Johnson·29 Jul 2021

I can't understand how you suppose to copy the color-hex code ! this is worse tool ever, you can see the code and you can't copy it, you can't even type it as once you move the mouse it's gone !!!
